People can't help being mentally ill

Don't label people with words like "crazy," "wacko," or "loony" or define them by their diagnosis.

Treat people with mental illnesses with respect and dignity, just as you would anybody else.

Mental illnesses are surprisingly common; they affect almost every family in America. Mental illnesses do not discriminate—they can affect anyone.

Behavior problems can be symptoms of emotional, behavioral, or mental problems, rather than merely attention-seeking devices.
